Combined application of SiO2 and TiO2 nanoparticles enhances growth characters, physiological attributes and essential oil production of Coleus aromatics Benth

Enhancing growth, vitality, and aromatic richness: unveiling the dual magic of silicon dioxide and titanium dioxide nanoparticles in Ocimum tenuiflorum L.

“…Conclusively, combined foliar application of Si 2 O and TiO 2 -NPs improves the quality of the essential oil by significantly enhancing the content and yield of Eugenol in the oil. In corroborations with our results Uddin et al. (2023) in Coleus aromaticus , Khan et al.…”

“…The application of growth-promoting substances has accelerated agricultural advancement, thereby enabling a partial realisation of the objective to enhance crop productivity ( Ahmed et al., 2022 ). Nanoparticles (NPs) have attracted significant attention in agriculture for their elicitor properties and potential to enhance plant growth, thereby improving overall crop productivity ( Mukarram et al., 2022 ; Uddin et al., 2023 ). Crop yields, nutrient loss, and disease prevention are all areas where nanomaterials could be utilised for betterment of agriculture.…”

“…The application of agrochemical sprays including fertilizers, nanoparticles, and elicitors, to the above-ground parts of plants is a globally recognised and effective agricultural practice ( Shahhoseini and Daneshvar, 2023 ; Yin et al., 2023 ). Furthermore, bioavailability, concentration, solubility, and exposure time are various factors which influence the uptake and distribution of metallic nanoparticles throughout a plant ( Uddin et al., 2023 ). Our findings demonstrate the significant impact of foliar application of SiO 2 -NPs and TiO 2 -NPs at various doses on the vegetative growth, physiology, and quality of O. tenuiflorum .…”

“…In another study, the application of Si-NPs boosted plant growth and biomass yield by decreasing the oxidative stress in lemongrass ( Mukarram et al., 2023 ) and wheat grains ( Hussain et al., 2019 ). Moreover, SiO 2 and TiO 2 -NPs have been found to improve the photosynthetic pigments in Triticum aestivum ( Tripathi et al., 2016 ) and Oryza sativa ( Rizwan et al., 2019 ; Zhang et al., 2020 ) plants and Coleus aromaticus ( Uddin et al., 2023 ). Our findings, demonstrated a significant improvement in growth characteristics ( Supplementary Table 1 ), photosynthetic pigments ( Figure 2 ), and chlorophyll fluorescence ( Figure 2 ) values mediated by combined treatment of SiO 2 and TiO 2 -NPs.…”

“…These results are in the agreement with the widely held view that CA and NR activities are intimately linked to nitrogen and carbon metabolism, respectively, thereby directly contributing to photosynthesis, growth, and biomass production of the crop plants ( Taiz et al., 2015 ). It has been revealed that the elevated Chl level has a stimulatory effect on photosynthesis, leading to an increase in the plant’s dry weight (DW) and fresh weight (FW) ( Ahmad et al., 2020 ; Uddin et al., 2023 ). Our findings are consistent with the study conducted by Morteza et al.…”
